How to Propagate String of Hearts? A Detailed Guide to the Latest Propagation Methods
String of Hearts is a succulent plant in the genus Ceropegia of the Apocynaceae family. It is often planted in plastic hanging baskets suspended beside doors and windows, with its stems and vines swaying in the wind, which is very interesting. When planted in ceramic pots and placed in indoor corners, on tall flower stands, or on top of bookcases, its stems and vines hang down and can reach about 150 cm, flowing freely and being very popular. Now let us take a look at how to propagate String of Hearts!
Cuttage Propagation
Cuttage is the most commonly used propagation method for String of Hearts. Generally, cut a stem segment with more than 2 nodes from the plant as a cutting, place the cutting in a ventilated place for about 10 minutes until the exuded liquid dries, then insert the cutting into the prepared growing medium, and cover it with plastic film to increase air humidity and speed up rooting. Under suitable temperature conditions, it will root in 2 to 3 weeks. When the roots grow to 2 to 3 cm, repot and transplant it.
Tubercle Propagation
Tubercle propagation is similar to cuttage propagation, except that the cutting bears tubercles. This method roots more easily than cuttage propagation and has a higher survival rate, but the production of tubercles requires a certain plant age and sufficient nutrients, so tubercles are rarely produced in home cultivation.
Air Layering Propagation
For air layering propagation, generally choose a robust growing branch, lay it flat on the growing medium, pierce a small wound at the node with a needle, then fix the node in the medium with a thin wire bent into a “u” shape, cover it with a small amount of medium, and keep it moist. After about 3 weeks, the node will be seen to swell and grow new roots. When the roots grow to 2 to 3 cm long, cut off this rooted stem segment and transplant it.
Note: String of Hearts can also be propagated by seed, but because seeds are not easily obtained in cultivation, this method is generally not used. In cultivation, attention should also be paid to the growing environment. String of Hearts likes diffused light and avoids direct strong light. It does not like fertilizer, and especially avoids high-phosphorus and high-potassium fertilizer. Because its roots have large tubers that can store nutrients and water, it is very drought-tolerant.
